Automotive radar interference mitigation by reconstruction and cancellation of interference component

Abstract

Automotive radar interference is an issue arising with the increasing amount of radar systems in automotive scenarios. Interference can influence the functionality of a radar system, e.g. decrease its detection capability. To ensure functionality in critical situations, interference countermeasures are applied. This paper proposes a countermeasure for chirp sequence modulated radars interfering one another estimating an interfering signals’ parameters to afterwards reconstruct and remove the interference.
